Jason Natural Cosmetics Tea Tree Shampoo Review

I am a natural, organic, green-friendly person.  I purchased this shampoo as I love tea tree oil and I have a need to balance my scalp in order for my fine hair to look decent and to avoid itchy dry scalp.  All I can say is....wow.  How could something so "natural" cause such a horrible reaction?  I broke out in hives for a week so bad that I couldn't even work.  I know that it was the shampoo that was the culprit because I took it to a biofeedback specialist and they identified it as the cause.  When they looked at the ingredients they ended up not being so "natural" after all.  I am not allergic to anything until now.  I would say if you have any kind of allergies, be careful about Jason products.  I still, unfortunately didn't pinpoint which unnatural ingredient caused the problem but I know it's not the tea tree oil because I use it in many of my other cosmetic products.  If I could sue for pain and suffering......just kidding.  I'm not hateful.  I just don't like this stuff.
